you dont use the metal spring cupos front or rear, these are part of the coilover unit.
up front fit the top mount direct to the shock and secure with the threaded bush, then fit to car and put the top cup on and secure either with a new nut or the nylock one from the coilover kit if supplied.
for the rear the only bit you need from the back is the 2 rubber bushes plus the bits that go between them and the car, you leave the old metal top cap and rubber spring seat off.
so 6, 7 10 and 12 here:

and everything from 13 upwards here:
